If you do a google search for 'horse chestnut leaf miner' and 'horse chestnut phytophthora', then you should get enough info to advise your customers. It's the leaf miner that makes the leafs go brown. http://arbtalk.co.uk/forum/showthread.php?t=3013&highlight=leaf+miner http://arbtalk.co.uk/forum/showthread.php?t=2153

Thanks Chris, I was still 'composing', when you posted this.

I am only speculating, but I have seen it demonstrated... You don't need any special skills or expertise to inject them and there are only so many chemicals available to choose from. I guess it's a case of making hay while the sun shines - i.e. before there is any competition. I think £500 a tree is getting a bit greedy though - unless of course there's only one tree to do and they're travelling a long way to do it. Obviously I don't know the facts, but if they're looking to charge the same amount per tree per annum for re-injections then it really does sound like money for old rope. Or am I missing something? (it won't be the first time)

£500.00 a tree? Not bad for 10 mins work, a pint of insecticide and no gaurantee.

I think they're smooth leaved elm - there are a few mature ones around, whether they're resistant strains or just lucky I don't know... There was a line of big mature elms on a nearby farm, which where fine up until this year - unfortunately the whole lot died in the summer. Oddly the three in the picture are surrounded by typical DED infected thicket growth, but they seem to survive, so perhaps they are resistant rather than lucky.
-
I finally got around to taking some pics of some elms that I pass regularly in the car... The two below are a huge tree in a back garden - check out the size of the trunk compared to the patio furniture: These two are of a group of 3 roadside trees:

Phaeolus schweinitzii might be a candidate??? -
Ganoderma resinaceum or Inonotus dryadeus
Giles Hill replied to stevelucocq's topic in Picture Forum
Here's one in it's early stages... I wrongly identified it as Iononotus, thanks partly to the amber coloured droplet. It subsequently changed into a big load of Ganoderma brackets, like the ones in Steve's picture. -

You're very welcome Monkeyd. I spotted this from the car and knew it was a Pholiota thanks to the recent pics you'd posted. Saying that... I think it's Poliota aurivella - the Golden Scalycap, but it looks a bit different to yours... What do you reckon? I'm wondering if your one might be Pholiota adiposa -that one likes beech trees apparently. -

Some kind of Boletus? -
Or possibly Fraxinus 'Raywood' - a popular variety amongst specifiers. It also falls to pieces allegedly...

Whilst not fool proof, I've found the short fungal section in 'Diagnosis of ill Health in Trees' to be useful. Basically it concentrates on the likely candidates i.e. the ones that are pathanogenic to trees - it subdivides them into toadstools, brackets etc. I've then usually been able to make a more positive ID by looking up images of the two or three that generally fit the description in the book. The main problem I've found with identifying something new is that some of them change so much in appearance through a season - and the books only have one or two images - that's where a web search can come in handy.

I think it's just what cherry bark does sometimes - it kind of peels.

You can download software that allows you to write on locked pdf files. The typewriter facility on this shareware one is ok: http://www.docu-track.com/home/prod_user/PDF-XChange_Tools/pdfx_viewer But it is a bit clumsy - I ended up buying the full version for about £20 I think it was, it's much better, I use it all the time.

I like trees but they're best ignored if you want to see the woods.:001_smile:

Still no eye dear. Thanks for the comments / guesses.
-
How far will it be planted from the house? How big is the garden? Is it being planted in a sunny or shady location? Is it in a place where the shade it casts in future might be a problem? Does it need to do a screening job? Would they prefer native or ornamental?
-
Collybia maybe?

Anyone for a wild guess?

Giant polypore from various angles. -
I'm glad you've but a pic of a British tree up. These two amaze me at the local level, because they're unusually big for the species: The first two are a parkland sycamore, the third one is a fairly well known crab apple in Bradfield woods.
-
I've asked a mate to send pictures of fungi that he finds on site surveys - to give me some extra practice. Does anyone have any ideas on these two - the first is on a sycamore, the second on a hornbeam. I've asked him to take pictures of the undersides next time... I was wondering if the one on the sycamore is Pleurotus? The hornbeam one looks like potatoes to me.

It amazes me that something so harmless looking could either be edible or completely deadly. It dosen't sound a very nice way to go either. Maybe best to to test it on the cat before you put it on your pizza...

From what I've read, they can be told apart by the volva - destroying angel and death caps are 'sack like'. False death cap has a trough like ridge at the top of the volva, around the stem. I'd say it's a white false death cap, comparing it to the pictures and info in Philips Mushrooms. That's not to say I'd take the Pepsi challenge with it.
